The multiple fundraising events - he held three in one day at the same Chicago venue earlier this month - are designed to help McCain improve upon his first-quarter total of nearly $13 million. McCain has expanded his "Young Professionals for McCain" events in which contributors who give less than the maximum $2,300 gather with the candidate. The next such event is May 23 on the rooftop of the D.C. law firm Covington & Burling LLP.
